Fury

Former cruiserweight world champion Bellew and ex-heavyweight title holder Haye had been due to renew their rivalry on December 17, only for the fight to be postponed after the latter tore his bicep in an accident on a stairwell.

Bellew claimed a stunning victory in their first meeting on March 4, defying the odds as Haye was rendered immobile by an ankle injury, leading his corner to throw in the towel in the 11th round.

Fury beat the Ukrainian in Germany at the weekend to take the WBA, IBF and WBO belts.

The contract for the fight included a clause for a rematch, for which the date and the venue have to be decided.

"Failure is not an option," said 39 year old Klitschko on his prospects of winning back his titles.
